Outline of Final Research Achievements

The present study examined the class-size effect on pupils' on-task behavior and teachers' individual instruction. We conducted experimental lessons with organizing 32-35 pupils large, 20 pupils medium, and 10-15 pupils small classes. We measured all of the participated pupils' body movement frequency as a sort of indices of on-task behavior with using accelerometer embedded wearable sensors and captured the numbers of teachers individual instruction . The results suggested these two of the following. Firstly, the larger the class size, the more off-task pupils increased, and the deviation of body movement frequency; one of the indices of on-task behavior, with reference to the whole-class trends became larger. Secondary, class size is one of the attribute that teachers' individual instruction implementation.
